Conquering Embodied Carbon Emissions for a Greener Future

Adapting Policy
Breakout 4: 3:10–4:10 p.m.

As greenhouse gas emissions from building energy use continue to fall due to energy code improvements, retrofits, and a lower carbon grid, the importance of tackling embodied carbon emissions from building products will keep rising. Liepa Braciulyte of New Buildings Institute will provide an introduction to embodied carbon and summarize building code proposals that Seattle is considering to require lower-carbon steel and concrete. Jess Harris from City of Seattle, Department of Construction and Inspections, will describe how permit incentives available for new construction can reduce building lifecycle embodied carbon. In addition, Sadie Carlson of Green Canopy NODE will translate emerging policy and embodied carbon research back to practice with a case study for a housing solution that leverages innovative construction techniques to optimize for embodied carbon, operational carbon, and cost. The investigation into the unique design advantages of cross-laminated timber in prefabricated modular construction outlines a systemic approach to decarbonization at scale. Furthermore, Jessica Martinez from DCI Engineers will present strategies that reduce the carbon footprint of concrete such as crafting efficient structural designs and coordinating procurement strategies that minimize carbon through mix design optimization and cement replacement.

Why Your Shower Feels Wimpy (And What You Can Do About It!)

Innovative Approaches
Breakout 3: 2–3 p.m.

In this session we will follow the water from where it enters a building through to a typical shower on the second floor. Along the way, we will discover the pressure losses, some avoidable, others not, that the water encounters. We will look at measured data from almost 70 combinations of pipe and fittings and from several tub/shower valves and examine how pressure compensating aerators and flow regulators improve system performance and customer satisfaction. Then we will show how using the IAPMO Water Demand Calculator (WDC) can be used to right-size pipes based on modern flow rates and plumbing materials. We will demonstrate that implementing these strategies can reduce the cost of complying with the 2021 WSEC-C for multifamily buildings by sharing the first cost and operational benefits of utilizing the WDC in apartment buildings that were built in 2020.

Morning Keynote: Change Is Here. And We Need More.

Ballroom
9–10 a.m.

Climate change is here. And it is here because we did not change. Now, in the face of an existential threat, we must change—change how we consume, change the technologies we use, change who we elect, and (yes) change our homes. We also need to change capitalism from a major contributor to creating the climate crisis to a force for positive change. “Climate Capitalism” is the idea that today, the best pathway for companies and industries to create enterprise value and outcompete their peers is by also creating climate value. This is not a pipe dream. It is happening today.
